dmesg from the freeze
Once the game gets to the menu screen (after intros) it shows a white screen (as expected, but for too long). After a few seconds the white screen goes away, the fan stops, the monitor goes into standby, and the whole os is unresponsive (no sysrq keys). Rebooting shows no sign that the kernel even knows anything happened (in dmesg, etc).
This only occurs if you use wine with glsl=enabled. glsl=disabled shows a semi-corrupt menu which you can exit without killing your system.
I'm on kernel 2.6.39-rc2 (built with NMI) and mesa git from 2011/04/08 (xorg-edgers ppa). The card is a Barts chip (6870), and glxinfo shows I'm using r600g. Wine is version 1.3.17.
If it matters, the NMI never comes. The kernel is built with CONFIG_FB_RADEON_DEBUG=y , but it's still rather quiet around the crash.
